PORTABLE FORGE.

SPECIFICATION forming part of Letters Patent No, 318,629, dated May 26,1885.

Application filed August 16, 1884.

To aZZ whom it may concern.-

Be it known that I, AUGUST KiiNIG, of Brooklyn, county of Kings andState of New York, have invented certain new and useful Improvements inPortable Forges, of which the following is a specification.

This invention has reference to an improved portable forge to be usedfor military purposes, railroad and bridge construction, and other workin which blacksmiths work has to be done at different places.

In the accompanying drawings, Figure 1 represents a side elevation of myimproved portable forge; Fig. 2, avertical longitudinal section of thesame; Fig. 3, a plan; and Fig. i, a vertical transverse section on liney 3 Fig. 3.

Similar letters refer to similar parts throughout the different views.

Referring to the drawings, A represents the body of my improved portableforge, whichis supported on wheels. Elliptic springs B are interposedbetween the front axle and the body of the forge, and semi-ellipticsprings, which rest on the hind axle, are connected at their ends tostuds a, projecting from the rear portion of the body.

At the rear part of the structure is a valved wind-chest, D, and belowsaid chest the bel' lows E E. Each of said bellows is composed of tworectangular boxes, I) b, one within the other. The upper boxes, I), arefixed to the wind-chest and the bottom of the wind-chest constitutes thetops of said boxes, the bottoms of the latter being open. The lowerboxes, I) b, are open at their tops, and have closed bottoms providedwith inlet flap-valves c c. The lower boxes slide vertically within theupper boxes and serve as pistons, being hinged at their bottoms to anoscillating lever, F, pivoted at its center to hangers G, attached tothe hind axle.

A handlever, H, is connected at its lower end to said oscillating leverfor actuating it, and extended upward and forward at one side of theportable forge to near the hearth thereof. As the lever F is oscillatedby the oscillations of the hand-lever H, the boxes I) 1) alternatelyrise and fall in the boxes I) I), one rising while the other is falling,whereby a (No model.)

continuous stream of air is forced into the wind-chest B through itsvalves (1 d, opening into said boxes I) I).

In a position of rest the hand-lever is supported by a socket, I,attached to a chain, I, at the side of the body A, as shown in Fig.

1. Vhen in use, the socket is detached from the hand-lever H, so thatthe latter can be oscillated, and thereby the bellows operated so as toproduce the wind for the hearth of the portable forge, the verticalmotions of the two bellows filling the wind-chest B with a uniformsupply ofair, which is conducted through the conducting-channel J to theperforated bottom of the hearth K, as shown in Fig. 2.

The hearth K is arranged at the front part of the body A and surroundedbyatransverse water-chamber, L. This water-chamber is open at one side,as shown in Fig. 4, so as to be conveniently filled, and is constructedwith an upwardly-projecting lip, e, at its mouth, so that the water willrise sufiiciently to cool not only the sides of the hearth, but also thetop plate of the watenchamber, which has the effect to concentrate thefire at the center of the 7 hearth and to keep the top plate cool, sothat tools can be placed thereon without becoming heated by the heat ofthe hearth. The hearth K is depressed at its center, the depression fbeing provided with openings f, through which the wind is forced againstthe fuel on the hearth, whereby the fire is kept up and intensified inthe usual manner in forges. The central space below the depressedportion f is closed by a slide, 5 which serves to receive the ashes orother particles which drop through the wind-openings.

A conical hood, M, provided with a chimney or smokestack, N, is adaptedto close over the hearth, said hood being provided with a door, 2', infront. The smoke-stack is steadied by and adapted to slide in a ring, j,connected to bracketarms K, attached to a toolchest, 0, located at therear of the structure. The rear side of the smoke-stack is provided 9 5with a toothed rack, Z, and a pin, j, in the ring j takes into the teethof the rack, so that the hood may be adjusted higher or lower forchanging the draft, supplying the fuel to or removing the ashes from thehearth.

\Vhen the lire is started, the hood is lowered so as to rest on the topplate or flange of the hearth, and the parts to be heated in the forgeare inserted through the hinged door t of the hood. The hood is providedwith handles m for conveniently lifting and lowering it. The uprightchest 0 at the rear part of the portable forge A is provided with hingedat the side. to which the wind comes, so as to form some protectionagainst the wind while working atthe forge. Vhen the forge is moved fromplace to place, the bench is swung inwardly and the hinged doors closed,so that the different working tools are protected against storm or loss.

The chambers P are provided with side doors, and may be utilized for thestoring of the anvil and other accessories used by blacksmiths. Thefront part of the forge is also used as a foot-rest for the driver whenthe forge is moved from place to place.

The advantages of my improved portable forge are that it can beconveniently transferred from place to place with all the accessoriesand instantly made ready for use; that a fire can be quickly startedwhenever required, and that the top and side walls of the hearth properare kept cool, so that the heat is concentrated at the center, andthereby the more efficient working of the hearth obtained.

The entire forge is preferably constructed of wrought and sheet metal,so that it is not exposed to injury by the influence of the weather, andis more durable, so as to require little repairing.

I claim as new and desire to secure by Letters Patent 1. The combinationof a wheeled body having a wind-chest and bellows at the rear part and ahearth at the front part, said hearth being connected with thewind-chest by an airchannel, substantially as set forth.

2. The combination, with a portable furnace, of an upright chest havinga hinged working-bench and hinged rear and side walls, the latter beingadapted to be thrown sidewise of the forge to protect the same againstthe wind, substantially as set forth.

3. The combination, with a wheeled vehicle, of a bellows and wind-chestat the rear part thereof, a hearth at the front part thereof, connectedwith said wind-chest, a vertically-adjustable hood and smokepipe, and athimble attached to bracket-rods, for supporting said hood andsmoke-pipe, substantially as set forth.

4. The combination, in a portable forge, of the bellows, afulerumedleverconnected therewith, a handle for operating said bellows, and aretaining socket and chain attached to the upper part of the forge forsupporting said handle, substantially as set forth.

5. The combination, in a portable forge, of the hearth, a water-chambersurroundingthe walls of the hearth, and a storage-chamber arranged infront of the water-c11amber and provided with hinged doors or covers,substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

AUGUST KONIG.
